The density of a certain material is such that it weighs 3 grams per fluid ounce of volume. Express this density in ounces per liter. Round your answer to the nearest hundredth.

Step-by-step explanation:

Let's start by converting 1) grams to ounces on one hand, and 2) fluid ounces to liters on the other:

1 gram = 0.035274 ounces

1 fluid ounce = 0.0295735  liters

Therefore, as we write the original density of 3 grams per fluid ounce, then we replace each unit by its equivalent in the units we want:

which rounded to the nearest hundredth becomes:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
